At first I got a free t-shirt from them and I was like "that's pretty cool!" then now since its so easy to earn these points I just got myself $5 Amazon gift card! Trust me this works! Just redeem like 5 amazon gift card which is $25, and buy yourself something nice.

Apples iCloud is not only good for purchasing apps on devices and streaming your music but also can bring deleted apps that are off the app store back from the dead. Here it is demonstrated with the app Tris, which was removed from the app store over 3 years ago. Theres nothing stopping iCloud.

iOS 5 allows you to sync your phone without cord and do it in background. Also if you have an iPad you notice if you already bought an app from the app store it changes its price description to INSTALL so you know which ones you bought. iOS 5 for iPhone does the same.

iOS 5, Apple’s new mobile operating system, was shown off at WWDC. As expected, the new version includes a brand-new notifications system, and system-wide social integration. Here’s everything you need to know:

FeaturesNotifications Center: all current iOS users know that the current notifications system was showing its age. Apple has turned that around by building a new system, which unobtrusively displays all notifications at the top of the screen, even during games, and on the Lock Screen. By sliding them down, users will be able to visualize all unread notifications, or dismiss them completely by hitting an "X" button next to them. Very straight-forward. Notification can include missed calls, voice mail messages (which can be played right from the Notifications Center and even notifications from other Apps.
This system is very similar to MobileNotifier, which isn’t surprising, since the company has recently hired its main developer.

Reminders: this feature, as the name implies, allows users to set different reminders for different times of the day, and different places. Thanks to the geolocation support present in devices, users can now configure Reminders to pop up a notification at a certain time and at a certain place, and even sync across devices using iCal. It’s really to-do lists on steroids!

Enhanced Safari: The iOS browser now looks a lot more like its desktop counterpart, with a few extra features of its own. Tabbed browsing now looks identical to the way it looks on the Windows and Mac versions, with tabs displayed across the top, at least on the iPad. The new Safari also brings the Reader feature, displaying a website’s content in an easy text only view, but unlike what happened before, users are now able to bookmark content onto a "Reading List" for later or send it to friends.

Twitter Integration: as rumored, the new iOS 5 includes deeper system-wide integration with Twitter. While there’s no support for other social networks, this feature is integrated with many apps, including the Camera App, allowing you to quickly tweet out what you’re working on. You can log into Twitter from System Preferences. It’s a single log in.

New Mail client: similarly to what happened in Lion, the iOS mail client is also receiving an upgrade. The App now supports draggable addresses, as well as the ability to flag messages and search them and dictionary lookup, by tapping on a word and selecting "Define".iMessage: it’s like iChat for iOS users. It lets you send text messages, photos, videos and even have group conversations, similarly to any other messaging client. This application is also a great new example of how Notifications Center, since this App interacts beautifully with it. With this out the gate, I one is left to wonder what will happen to iChat.Independence from computers: Previous versions of iOS required users to connect them to a computer in order to set them up, update them or sync them. iOS 5 will put an end to all that, by allowing users to update the device over-the-air. There’s also a new set-up wizard for new devices, allowing them to be configured for the first time without the need for a desktop computer. Can those who hate iTunes finally proclaim victory?

Tens of small additions: iOS 5 includes a number of small improvements, such as direct game downloads in the Game Center, a new optional keyboard, enhancements to the Music App on the iPad and an enhanced Camera app.Availability
If you’re a developer and have an iPhone 4 or 3GS, a 3rd or 4th generation iPod touch or a first or second-gen iPad, you’ll be able to grab iOS 5 from Apple Developer Center today for testing purposes, so you can get your Apps ready for many of the features we’ve talked about, such as Notifications Center.
Regular users would be able to grab the software for free later this fall. For more details, check this article.Jailbreak?
Those using a jailbroken device must be warned that no jailbreak solution is available at the moment. Upgrading to the new software will break your jailbreak. You can read more about the state of jailbreaking on an editorial I wrote up yesterday.

According to Apple itself, iOS 5 will allow automatic over-the-air App updates. This was confirmed by the iTunes App Update page, which alluded to the new feature.

If you own an iOS device and have apps installed on it, you’re probably familiar with this page. You’re redirected to it whenever you select "Check For Updates" on the iTunes App section. As of a few hours ago, it had this bit of extra text

Currently, over-the-air updates are possible, although not automatically, requiring users to launch the App Store in order to get updates, which can be extremely time-consuming on slow networks. Automatic updating would make the update process essentially invisible to the user and still provide the same results. It’s unclear whether over-the-air updates would only apply to apps or to iOS itself as well, much like Android, Google’s competitor to Apple’s iOS.
While the reference to this feature has since been removed from iTunes, that didn’t happen before screenshots were all over Twitter, and later confirmed by credible people. There’s a very slight chance that we won’t see this announced next week, now that Apple openly disclosed it, although not intentionally.

This isn’t the first time that we’ve seen an Apple product being unveiled ahead of time by accident. In 2003, the specs of the then-unreleased PowerMac G5 were accidentally posted on the PowerMac G4′s page; and in 2006, references to iWeb, also rumored and unreleased at the time, were found on Apple’s support page. Both of those products were officially announced days later.
Last week, Apple confirmed it would be unveiling iOS 5, as well as Mac OS X Lion and iCloud, a new internet service at WWDC. While we don’t yet know any official details about those products, rumors of both iOS 5 and iCloud have been ongoing for months. It’s predicted that Apple’s new mobile operating system will include a new, less intrusive notification system, enhancements to multi-tasking and widgets, much like Google’s Android. Yesterday, we reported on a new artist’s mockup of what the new version of iOS should look like, based on the most popular rumors.
WWDC, Apple’s yearly developer conference, will kick off on June 6th. Although much of its focus will be to inform and train developers on the company’s newest software advancements, consumer products are often announced there as well.

One of the major irritations with the way iOS works is the inability to backup your app data without the need to connect your device to iTunes. Going one step further, wouldn’t it be great if apps across multiple devices could stay in sync, using the magic of the cloud?
If you’re the jailbreaking type, then you’re in luck!

A new app going by the name if DataDepost (free in Cydia) does exactly what we’ve all bee crying out for.
Have a brilliant city saved in Sim City and want to continue it on your iPod touch? Using DataDeposit you can back up your game data to Dropbox and pull it onto your iPod touch. No fuss, no mess.
What DataDeposit does is scan your device for apps it can back up and then allows you to do just that. What you’re left with is a folder on your Dropbox account with subfolders for each app.
DataDeposit is just another app that makes jailbreaking a no-brained these days – at least until Apple pulls its finger out!

If you cast your minds back a couple of months, you’ll remember how we told you that AT&T had begun clamping down on people using tethering on their iPhones without paying for the upgraded tethering plan. Emails and SMS messages were sent informing customers that if they continued to tether they would be charged for it. At the time we weren’t sure how AT&T knew which people were actually tethering, but now we do and more importantly, we know how to get around it.
Today iPhoneDownloadBlog pointed out a snippet from a post over on AndroidPolice that is of particular interest to unauthorized iOS tethering users. Turns out they know how AT&T was able to tell when customers were tethering.

“Jailbroken iPhones typically use the same tethering technique as a standard iPhone, the one that’s already present in iOS. This method exposes tethering activity quite readily, because the iPhone, when in tethering mode, sends traffic through an alternate APN (AT&T access point/router) for the express purpose of identifying the traffic as tethered data. This makes it extremely easy for AT&T to identify whether or not an iOS device is utilizing tethering, and just how much of their data is consumed via tethering.
Some tethering applications for iOS make use of alternative methods and route tethered traffic through the phone’s normal data APN, but by and large, most jailbreakers stick with the stock application because it’s easy to use and doesn’t require any complicated setup. In fact, many iPhone users jailbreak for the sole purpose of avoiding AT&T’s tethering fees (for why, see next section). These are the people AT&T’s is going after.”

So it appears, apps that use the special data APN get noticed by AT&T’s systems, hence the strong-arm tactics. Popular jailbreak app MyWi works just as described by AndroidPolice – using the tethering APN. What we need is an app that uses the same APN as your iPhone does for its own data. According to the iPhoneDownloadBlog, that app is PdaNet.

The latest version of PdaNet comes complete with an option specifically for hiding tethering from AT&T – presumable this option changes the APN the app uses for routing data. TetherMe is another app that appears to be one AT&T can’t track, though PdaNet does seem to be the best bet if you want to avoid your carrier’s tethering charges.
So, if you’re not too keen on paying for your data twice, jailbreak your iPhone and give PdaNet a whirl – it’s available via Cydia right now.

The iPhone Dev-Team has released Redsn0w 0.9.6rc13 to include support (except for iPad 2) for untethered jailbreak on iOS 4.3.2 using the same i0n1c’sexploit which was used to previously untether 4.3.1.
iOS 4.3.2 was originally jailbroken last week using PwnageToolbundles (on Mac) but it was limited to tethered boot. But now with this latest version of Redsn0w, you can jailbreak your iPhone, iPad, and iPod touch fully untethered on the latest iOS 4.3.2 firmware.NOTE: Those of you who rely on a carrierunlock MUST STAY AWAY from Redsn0w and stock iOS 4.3.2 firmware.

How to jailbreak iOS 4.3.2 using Redsn0w on Windows and Mac:Step 1: Download iOS 4.3.2 for iPhone, iPad or iPod touch. (download links given at the bottom)Step 2: Update/Restore to iOS 4.3.2 firmware using the IPSW file you just downloaded via iTunes 10.2.2.Step 3: Start Redsn0w and point it to the official iOS 4.3.2 firmware file.

Step 4: Now select “Install Cydia” and click “Next”. Optionally (if available), you can also select any other option you like.

Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
At this stage you will be presented with a screen where you will be guided on how to enter DFU mode. Quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.

Step 6: Sit back and enjoy while Redsn0w does the rest for you. Once done, your iPhone, iPad or iPod touch will restart automatically and you will find it fully jailbroken (untethered) on the latest iOS 4.3.2 firmware.UPDATE 1: Redsn0w 0.9.6rc14 adds support for untethered iPhone 4 jailbreak on iOS 4.3.2. Download it from here.

The iPhone Dev Team today has released an updated version of Ultrasn0wunlock to fix signal bar issues on iOS 4.3.1 compatible iPhones, running on the old baseband.

We’ve pushed out the 4.3.1 compatibility fix for ultrasn0w in Cydia — it’s now at version 1.2.1. If you’re not already at 4.3.1 and you need the unlock, please be sure you understand how to get to 4.3.1 using a custom IPSW that doesn’t update your baseband.This isn’t a new unlock! It’s to allow those who are already unlocked to use FW 4.3.1. It also fixes the signal bar issue for those who aren’t using the unlock but retain an older baseband intentionally.AFTER INSTALLING ULTRASN0W 1.2.1, PLEASE REBOOT YOUR iPHONEusing the normal “slide to power off” swipe. T-Mobile users in the USA also should disable 3G mode in Settings->General->Network.

However it should be noted that this release of Ultrasn0w is not a new unlock for iPhones with newer basebands, instead, it only fixes the compatibility and signal bar issues on the existing devices, which are jailbroken (with preserved basebands: 01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00) on iOS 4.3.1 using PwnageTool or Sn0wbreeze.For iPhone 3GS Only: How to Update iPhone 3GS to 06.15.00 Baseband for Unlock: Ultrasn0w 1.2.x unlocking requires that your iPhone 3GS is jailbroken with 06.15.00 baseband. Follow the complete guide posted here (with PwnageTool) or here (for Redsn0w) to update your iPhone 3GS baseband to 06.15.00 and jailbreak it on iOS 4.1 / 4.2.1 before proceeding with the following steps.
Note: Updating iPhone 3GS baseband to iPad’s 06.15.00 might result in loss of GPS functionality.Step 1: First up, you will have to jailbreak your iPhone 4 or 3GS on iOS 4.3.1 and preserve the old baseband using either PwnageTool on Mac, or Sn0wbreeze on Windows. Instructions on how to jailbreak iOS 4.3.1 using PwnageTool can be found here, and for Sn0wbreeze can be found here.Step 2: Once you are done with the jailbreak, you can now unlock your iPhone on the supported basebands using Ultrasn0w 1.2.1 from Cydia. To do this:

Start “Cydia” on your iPhone.

Touch on “Manage” tab on the bottom.

Now touch on “Sources” as seen in the screenshot below:

Touch on “Edit” and then on “Add”. You will be prompted to enter a url source as seen in the screenshot below. Type “http://repo666.ultrasn0w.com” and touch on“Add Source” to add this repo if you haven’t already.

Cydia will now automatically update your sources by following a series of automated steps.

After installation is completed. Search for “ultrasn0w 1.2.1” in Cydia and install this application. This app will automatically unlock your iPhone so that you can use it with any carrier.

Step 3: Now simply restart your iPhone and voila! you should now have a fully unlocked iPhone 4 or 3GS, running iOS 4.3.1 !

Sn0wbreeze 2.5 is now available for Windows users to fully jailbreak iOS 4.3.1 untethered running on iPhone 4, 3GS, iPad (1st-gen) and iPod touch. Just like the new PwnageTool 4.3 for Mac, Sn0wbreeze 2.5 for Windows also uses the same new untether exploit to jailbreak all devices (except for iPad 2 ) on the latest iOS 4.3.1 firmware, and at the same time will help retain the old baseband for iPhone 4 and 3GS users so that they can be unlocked using Ultrasn0w.

For Mac users, we have already covered extensive tutorials on how to jailbreak iOS 4.3.1 using PwnageTool:

NOTE: If your iPhone doesn’t rely on a carrier unlock, you can use Redsn0w for both Windows and Mac to easily jailbreak your device on iOS 4.3.1. Complete step by step instructions can be found here.Step 1: First up, download all the required tools and files to your Windows desktop:

Note: If your iPhone relies on a unlock, proceed only by selecting “Baseband Preservation Mode” option instead of “Expert Mode”.
Since building custom firmware may take some time, you can optionally play Pac-Man game to kill some time.

Step 6: Sn0wbreeze will greet you with the following “Done!” message when the custom firmware has been successfully created.

Step 7: Now follow the onscreen steps to enter DFU mode using Sn0wbreeze:

Hold Power and Home buttons for 10 seconds

Now release the Power button but continue holding the Home button for 10 more seconds

You device should now be in DFU mode

If you have followed the steps correctly, you will get the following message from Snw0breeze

Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold Left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in iTunes and then release this button.

This will make iTunes prompt you to select the location for your custom firmware 4.3.1 file. Select the required custom .ipsw file that you created above, and click on “Open”.

Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.3.1 on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on iOS 4.3.1.

The just released PwnageTool 4.3 can jailbreak iOS 4.3.1 on iPhone 4, 3GS, iPad (1st-gen), iPod touch 4G/3G, Apple TV, and at the same time will help retain the old baseband for iPhone 4 and 3GS users so that they can unlock using the existing version of Ultrasn0w.
If your iPhone doesn’t rely on a carrier unlock, you can use Redsn0w for both Windows and Mac to easily jailbreak your device on iOS 4.3.1. Complete step by step instructions can be found here.
Unlike the last release, this version of PwnageTool brings full untethered iOS 4.3.1 jailbreak for all devices except for the iPad 2. This untethered jailbreak for iOS 4.3.1 is based on an exploit found by iPhone security expert and hacker Stefan Esser, who demoed it on his iPod touch last week before handing it over to the Dev-Team to do the rest.
iOS 4.3.1 was originally jailbroken last week using PwnageToolbundles (on Mac) and Sn0wbreeze (on Windows) but it was limited to tethered boot.

Step 6: PwnageTool will now create the custom .ipsw file for your iPhone, iPad or iPod touch which will be jailbroken.

Step 7: Now follow the following steps to enter DFU mode using PwnageTool:

Hold Power and Home buttons for 10 seconds

Now release the Power button but continue holding the Home button for 10 more seconds

You device should now be in DFU mode

Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold left “alt” (option) button on Mac, or Left “Shift” button if you are on Windows on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.
This will make iTunes prompt you to select the location for your custom firmware 4.3.1 file. Select the required custom .ipsw file that you created above, and click on “Open”.

Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.3.1 on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on iOS 4.3.1.

The latest line to come out of the Apple rumor-mill is iOS-related and iOS 5 to be specific. According to a report by TechCrunch the much vaunted Siri could be the secret ingredient in the next major mobile operating system release to come out of Cupertino.
Bought by Apple last year, Siri is an iOS app that allows users to perform tasks using simple, real English commands. An example would be asking the app what is playing at a particular venue. The app would then go off and find out. No search criteria, no modifiers.

Expected to be announced at WWDC in June, iOS 5 is touted as a major new release for iOS, with more than a few new features expected. Siri’s integration deep into the operating itself could open iDevices to a new world of true hands-free operation. This could be especially true if rumors of the feature being opened up to developers are accurate.

We think we live in the future now thanks to our touch-screen phones and tablets. You just wait until we’re telling our hardware what to do just using our voices!

After demoing his untethered jailbreak on iOS 4.3.1, iPhone security expert and hacker Stefan Esser has confirmed that he has now handed over the exploit to the members of the iPhone Dev-Team and that it is currently in internal beta testing stage.

Once this initial testing is found to be successful, they are then going to implement it in one of their existing tools like Redsn0w or PwnageTool before releasing it to public.

Apple has officially confirmed the schedule for WWDC 2011. It is going to be held from 6th to 10th of June – at Mascone Center in San Francisco. A lot of exciting things are on the horizon for this conference, including great opportunities for developers and hopefully the unveiling of the next iPhone, along with iOS 5, Mac OS X Lion.

(Here's a little picture I made for you iPhone or iPod Touch users to save this picture.)

We will cover the event and it’s details very extensively so stay tuned! We’re as excited as you guys are, this is huge event and we believe none of you would want to miss it!
Full press release is as follows:

Managed to get your PS3 banned from the PlayStation Network? It’s annoying right? All those lovely demos and media could be at your finger-tips, but alas you just can’t quite reach. Well now you might just be able to fix that thanks to a post over at PS3Hax.

This is confirmed to work if the error you receive when trying to access the PSN is error number 8002A227.
You’ll be needing: PS3DNS-GUI and PSID.
Sitting comfortably? Then we shall begin:

Download the above mentioned required files (obviously enough).

Run PS3DNS-GUI and choose your IP and region.

Go to Tools – Rewrite – PS3DNS – eth0 – Rules – Add

Enter every field just as it is in the image below. The part that says ‘original console ID’ will need the ID from the banned machine, No spaces!

Change the last digit of your ID to 1.

Hit OK.

On your PS3 and in your network settings, enter your DNS as your PC’s IP. Turn on Proxy and enter your PCs IP as the Host and 8888 in Port.

Fingers crossed, and that should do the trick. Any problems please do visit the PS3Hax post – there are loads of comments there with people getting the method to work and helping each other through the process.
Good luck!Disclaimer Note: This article is purely for informational and testing purposes only. We at Darth2499 Blog did not create the hack, nor do we endorse or promote the use of it. We are not responsible for any bans that may occur, or the inability to sign-in to PSN. Use it at your own risk only.

Remember the date folks – today is the day Apple (and Firemint) changed the video gaming world.
In a video posted to the company’s blog, Firemint has showed off a new update that is coming to its popular iPad game, Real Racing 2 HD. Said update brings the ability to take the Digital AV cable, plug it into your shiny new iPad 2, and play take your racing to the big screen.

And we’re not talking boring old mirroring here either.
The video shows Real Racing 2 HD running on a large TV in glorious 1080p, with the iPad screen showing a different game UI. It. Looks. Gorgeous.

No word yet on a release date for the update, but if this is where iPad gaming is going, sign me up! Oh, and imagine this running over AirPlay instead of a cable.
Blown your mind, right? Mine too.

PwnageTool bundle for jailbreaking the first-generation iPad on the latest iOS 4.3.1 is now available. You can use this bundle with PwnageTool 4.2 to create custom jailbroken 4.3.1 firmware files.

This works for iPhone 3GS/4 and iPod touch 4G and also iPad 1. (JUST DOWNLOAD THE RIGHT BUNDLE)

Support for iPhone 3GS and iPod touches is on the way ! Simply follow the instructions below to jailbreakiOS 4.3.1 on iPhone 4 using a combination of PwnageTool 4.2, Universal Ramdisk Fixer and tetheredboot utility.Here’s what you will need(Download link below):

There is no unlock for the new baseband on iOS 4.3.1. If your iPhone relies on a carrier unlock, DO NOT update to stock iOS 4.3.1.

iPad 2 users on iOS 4.3 should stay away from iOS 4.3.1 until further confirmation.

Cydia is fully working on iOS 4.3.1

It is a semi-tethered jailbreak.

Your baseband will not be upgraded during restore process.

Hacktivation is supported.

Modifying PwnageToolStep 1: Download PwnageTool bundle (includes Universal Ramdisk Fixer) for your version of iOS device. Extract the .zip folder, in there you will find a .bundle file, for this guide, we are using iPhone 4 bundle iPhone3,1_4.3.1_8G4.bundle. Move this file to your desktop.Step 2: Download PwnageTool 4.2 and copy it to /Applications directory. Right click, and then click on “Show Package Contents” as shown in the screenshot below.Step 3: Navigate to Contents/Resources/FirmwareBundles/ and paste iPhone3,1_4.3.1_8G4.bundle file in this location.

Creating Custom Ramdisk for iOS 4.3.1 Custom FirmwareStep 4: Download Universal Ramdisk Fixer (part of the PwnageTool bundle package that you downloaded in Step 1 above) and simply install it as shown in the screenshots below. This is important because Ramdisk in the current version of PwnageTool is broken. This Universal Ramdisk Fixer basically patches it correctly for iOS 4.3.1 firmware.

Step 7: Browse for iOS 4.3.1 firmware for your deviceStep 8: Now select “Build” to start creating custom 4.3.1 firmware fileStep 9: PwnageTool will now create the custom .ipsw file for your iPhone which will be jailbroken.Step 10: Now follow the following steps to enter DFU mode using PwnageTool:

Hold Power and Home buttons for 10 seconds

Now release the Power button but continue holding the Home button for 10 more seconds

You device should now be in DFU mode

Restore iOS 4.3.1 Custom Firmware Using iTunesStep 11: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold left “alt” (option) button on Mac, or Left “Shift” button if you are on Windows on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.
This will make iTunes prompt you to select the location for your custom firmware 4.3.1 file. Select the required custom .ipsw file that you created above, and click on “Open”.Step 12: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.3.1 on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on iOS 4.3.1.Booting in Tethered Mode
Last but not the least, since there is no untethered jailbreak for iOS 4.3.1 yet, we will have to boot it into a tethered jailbroken state. To do this, we will make use of a utility named “tetheredboot” as shown in the steps below.Step 13: Download tetheredboot.zip utility for Mac OS X and extract the .zip file.Step 14: First, we will need two files from the custom iOS 4.3.1 firmware namely: kernelcache.release.n90 and iBSS.n90ap.RELEASE.dfu. To do this, make a copy of your custom iOS 4.3.1 file that you created above, change the extension of this file from .ipsw to .zip, and then extract this .zip file.
Now copy kernelcache.release.n90 file, and then copy iBSS.n90ap.RELEASE.dfu files which are found under /Firmware/dfu/.
Move all these files, and tetheredboot utility to a new folder named “tetheredboot” on the desktop as shown in the screenshot below.

Step 15: Turn off your iOS device, and start Terminal on OS X and run the following commands:

You will have to of course replace “TaimurAsad” with the name of the directory on your computer.
now press enter.
NOTE: If the above fails, try ‘tetheredboot -i ibss -k kernel’ instead of ‘tetheredboot ibss kernel’:

You should now see some code running in the Terminal window, at some point, it will ask you to enter DFU mode. Now follow the following steps to enter DFU mode:

Hold Power and Home buttons for 10 seconds

Now release the Power button but continue holding the Home button for 10 more seconds

You device should now be in DFU mode

Now wait for your device to boot, Terminal at this point will be showing “Exiting libpois0n” message. After a short while, your iPhone, iPad or iPod touch will be booted in a jailbroken tethered mode !
